I just posted a comment on 1060580 about marking it as a duplicate of this bug. I also had this to add:
On Ubuntu 13.10, it's worth noting that disabling the Unity plugin in CCSM eliminates bug 1060580 and this one. Interestingly, re-enabling the Unity plugin then trying drag and drop again, the panel fade animation doesn't occur, and neither do these two bugs. I'm pretty confident that narrows these bugs down to the panel fade animation. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

It is important that "drag-leave" not be fired until the mouse actually leaves the widget. However, when running unit, "drag-leave" will be fired ~1 second after a drag begins. Here is a test project (in Vala) that reproduces the issue. Select a file on your desktop, and drag it to the window that this test project creates. You must drag it to the window within ~1 second to reproduce the bug. You should see "in on_drag_leave" appear in stderr, despite the mouse remaining within the Window. void main(string[] args) { Gtk.init(ref args); new MainWindow(); Gtk.main(); } public class MainWindow : Gtk.Window { private const string URI_LIST_MIME_TYPE = "text/uri-list"; public MainWindow() { destroy.connect(Gtk.main_quit); set_size_request(450, 50); title = "Main Window"; Gtk.Widget destination = new Gtk.Label("Drag a file here"); const Gtk.TargetEntry[] target_entries = { { URI_LIST_MIME_TYPE, 0, 0 } }; Gtk.drag_dest_set(destination, Gtk.DestDefaults.MOTION | Gtk.DestDefaults.HIGHLIGHT, target_entries, Gdk.DragAction.COPY); destination.drag_data_received.connect(on_drag_data_received); destination.drag_drop.connect(on_drag_drop); destination.drag_leave.connect(on_drag_leave); add(destination); show_all(); } private void on_drag_data_received(Gtk.Widget sender, Gdk.DragContext context, int x, int y, Gtk.SelectionData selection_data, uint info, uint time_) { bool dnd_success = false; if (selection_data.get_length() >= 0) { string string_data = (string)selection_data.get_data(); stderr.printf("Received %s: '%s'\n", URI_LIST_MIME_TYPE, string_data); dnd_success = true; } Gtk.drag_finish(context, dnd_success, false, time_); } private bool on_drag_drop(Gtk.Widget sender, Gdk.DragContext context, int x, int y, uint time_) { if (context.list_targets() == null) return false; uint length = context.list_targets().length(); Gdk.Atom? target_type = null; for (uint i = 0; i < length; i++) { Gdk.Atom target = context.list_targets().nth_data(i); if (target.name() == URI_LIST_MIME_TYPE) target_type = target; } if (target_type == null) return false; Gtk.drag_get_data(sender, context, target_type, time_); return true; } private void on_drag_leave() { stderr.printf("in on_drag_leave\n"); } } ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: unity 5.12-0ubuntu1.1 ProcVersionSignature: Ubuntu 3.2.0-25.40-generic 3.2.18 Uname: Linux 3.2.0-25-generic x86_64 ApportVersion: 2.0.1-0ubuntu8 Architecture: amd64 CompizPlugins: [core,composite,opengl,compiztoolbox,decor,vpswitch,snap,mousepoll,resize,place,move,wall,grid,regex,imgpng,session,gnomecompat,animation,fade,unitymtgrabhandles,workarounds,scale,expo,ezoom,unityshell] Date: Tue Jun 26 18:06:07 2012 InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Release amd64 (20120425) SourcePackage: unity UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1018215/+subscriptions -- Mailing list: https://launchpad.net/~dx-packages Post to : dx-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~dx-packages More help : https://help.launchpad.net/ListHelp
